How to integrate Mem0 MCP with ChatGPT

ChatGPT is one of the most popular AI tools today, with capabilities ranging from deep research and image generation to writing, coding, and everyday productivity.

In this guide, I will explain the easiest and most secure way to connect your Mem0 account to ChatGPT via Composio Connect, so it can summarize unread updates from this morning, create draft replies to urgent messages, fetch contact details for recent senders, and more without ever putting your account credentials at risk.

Why use Composio over default connectors?

  • Apps with read and write access. Default connectors mostly can read your data. Composio's Mem0 integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
  • 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
  • Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

Prerequisites

  • A ChatGPT account with Plus subscription or higher (Business, Enterprise, Edu, or Pro). We will use ChatGPT Web.
  • Access to the Mem0 workspace you want to connect.
  • Composio MCP.

Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.

4. Start using Composio

Composio tools are now available in ChatGPT chats and Deep Research. In every new chat, click the + icon at the bottom, click More, and select Composio to enable tools for that conversation.

What you can do after connecting Mem0

  • Store meeting notes from today's call
  • Export all project memories as CSV
  • Add new user to our team space
  • Search recent notes mentioning quarterly goals

Security + privacy notes (important)

  • Use least-privilege access: Only grant permissions you actually need.
  • Review OAuth permissions before approving: Make sure requested scopes match what you expect Composio and ChatGPT to do.
  • Keep write actions human-reviewed: For actions like sending messages, creating labels, or editing drafts, keep manual confirmation enabled.
  • Be careful with sensitive data: Avoid using this setup with highly sensitive information unless allowed by your personal, company, or client policies.
TOOLS

Supported Tools

Every Mem0 action and event your agent gets out of the box.

Add member to project

Adds an existing user to a project (identified by `project_id` within organization `org_id`), assigning a valid system role.

Add new memory records

Stores new memory records from a list of messages, optionally inferring structured content; requires association via `agent_id`, `user_id`, `app_id`, or `run_id`.

Add organization member

Adds a new member, who must be a registered user, to an organization, assigning them a specific role.

Create a new agent

Creates a new agent with a unique `agent_id` and an optional `name`; additional metadata may be assigned by the system.

Create a new agent run

Creates a new agent run in the mem0.

Create a new application

Creates a new application, allowing metadata to be passed in the request body (not an explicit field in this action's request model); ensure `app_id` is unique to avoid potential errors or unintended updates.

Create a new organization entry

Creates a new organization entry using the provided name and returns its details.

Create a new user

Creates a new user with the specified unique `user_id` and supports associating `metadata` (not part of the request schema fields).

Create memory entry

Lists/searches existing memory entries with filtering and pagination; critically, this action retrieves memories and does *not* create new ones, despite its name.

Create project

Creates a new project with a given name within an organization that must already exist.

Create webhook

Creates a new webhook for a specific project to receive real-time notifications.

Delete an organization

Permanently deletes an existing organization identified by its unique ID.

Delete memory by id

Permanently deletes a specific memory by its unique ID; ensure the `memory_id` exists as this operation is irreversible.

Delete entity by type and id

Call to permanently and irreversibly hard-delete an existing entity (user, agent, app, or run) and all its associated data, using its type and ID.

Delete memories

Deletes all memories matching specified filter criteria.

Delete memory batch with uuids

Deletes a batch of up to 1000 existing memories, identified by their UUIDs, in a single API call.

Delete project

Permanently deletes a specific project and all its associated data from an organization; this action cannot be undone and requires the project to exist within the specified organization.

Delete project member

Removes an existing member, specified by email address, from a project, immediately revoking their project-specific access; the user is not removed from the organization.

Delete webhook

Deletes a webhook and stops receiving notifications for the specified webhook ID.

Export data based on filters

Creates a new memory export job with optional entity filters (user_id, agent_id, app_id, run_id).

List organizations

Retrieves a summary list of organizations for administrative oversight; returns summary data (names, IDs), not exhaustive details, despite 'detailed' in the name.

Fetch details of a specific organization

Fetches comprehensive details for an organization using its `org_id`; the `org_id` must be valid and for an existing organization.

Get list of entity filters

Retrieves predefined filter definitions for entities (e.

Get entity by id

Fetches detailed information for an existing entity (user, agent, app, or run) identified by its type and unique ID.

Get event status by event ID

Retrieves a single async event by ID to check its current status and results.

Tool to retrieve all memories associated with a specific entity (user, agent, app, or run).

Get memory export

Retrieves the status and results of a memory export job by its ID.

Perform semantic search on memories

Searches memories semantically using a natural language query and metadata filters.

Remove a member from the organization

Removes a member, specified by their username, from an existing organization of which they are currently a member.

Retrieve all events for the currently logged in user

Retrieves a paginated list of events for the authenticated user, filterable and paginable via URL query parameters.

Retrieve memory history by id

Retrieves the complete version history for an existing memory, using its unique `memory_id`, to inspect its evolution or audit changes.

FAQ

Frequently asked questions

With a standalone Mem0 MCP server, the agents and LLMs can only access a fixed set of Mem0 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Mem0 and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. ChatGPT fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Mem0 tools.

Yes, absolutely. You can configure which Mem0 scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Mem0 data and credentials are handled as safely as possible.
